ignore generator auto start, when shore power is connected

Finally I will install my auto start/stop panel of my generator.

And now I would like to use the functionalities of the CCGX!

But how to ignore the the auto start, when shorepower is connected to AC2?

The answer is to use AC In 1 for shore power and AC In 2 for generator.

AC In 1 has priority over AC In 2. Which you connect to grid and generator depends on grid reliability/robustness.

Victron recommends AC In 1 for generator in "weak grid" situations, where the grid isn't always capable of supplying the load. In this case, the Quatro will supply the load from the batteries, then start the generator when low state of charge or high load thresholds are reached.

However if the grid can supply the load, there's no reason to call on the generator to take over and it makes sense to give grid priority over generator.

The rest of the solution is to turn on "Do not run generator when AC1 is in use". That setting is in the generator start/stop conditions.

There's more about setting up for generator control here:

BTW, this only works for Quatro inverter/chargers since Multi only has one input. In the case of a Multi, the switch between grid and generator must be made up stream of the Multi and CCGX has no way of knowing which source is active or present.

Thanks!
Always wondered why the suggestion was AC1 to Generator

The start signal cable that comes from the CCGX relay could be connected in series through a second relay of the Quattro. With the Programmable-Relay-Assistant switch of the relay if AC In 2 is active. Then the start signal will not get through to the generator if AC In 2 is active.
